INTRODUCTION: Placenta is a vital organ with highly specialized functions. According to the Perinatal Section of the Pediatric Pathology Society, placental histopathological abnormalities are typically categorized into maternal vascular hypoperfusion, fetal thrombotic vasculopathy, and inflammatory lesions. This study aims to assess the placental histopathological abnormality results in relation to adverse obstetric outcomes and to investigate whether specific placental abnormalities are associated with particular adverse outcomes.
METHODS: A retrospective cross-sectional study was conducted between January 2017 and January 2020 including all women who were admitted to Sultan Qaboos University Hospital with an adverse obstetric outcome who met the inclusion criteria, and whose placentas were sent for histopathological examination.
RESULTS: A total of 191 women were included in the study. The most common adverse obstetric outcomes included preterm labor (25.1%), fetal growth restriction (FGR) (19.4%), preeclampsia and related complications (15%), placental abruption (14.1%), and chorioamnionitis (14%). 74% of women had abnormal placental findings. Among women with preterm labor, inflammatory lesions were present in 56.3% of cases (p = 0.006). Fetal thrombotic vasculopathy lesions were present in 13.5% of FGR cases (p = 0.037). In preeclampsia cases, maternal under perfusion lesions were present in 79% of cases (p = 0.013).
CONCLUSION: Placental histopathological examination is an important tool for assessing perinatal outcomes. Correlating placental findings with specific obstetrical conditions and adverse outcomes provides valuable information that can assist obstetricians in developing appropriate management plans for future pregnancies.
